A manufacturer of potato chips would like to know whether its bag filling machine works correctly at the 405 gram setting. It is believed that the machine is underfilling the bags. A 22 bag sample had a mean of 396 grams with a variance of 441. A level of significance of 0.1 will be used. Assume the population distribution is approximately normal.
Required:
State the null and alternative hypotheses.
Answers
Answer:
We reject H₀
Step-by-step explanation:
Normal Distribution with n = 22 ( sample size)
n<30 we need to use a t-student distribution
Sample mean μ = 396
Population mean ( required mean ) μ₀ = 405
Sample variance is 441 then sample standard deviation s = √441
s = 21
Hypothesis Test
Null Hypothesis H₀ μ = μ₀
Alternative Hypothesis Hₐ μ < μ₀
Significance level α = 0,1
The test is a one-tail test to the left
From t-student table we find for t(c)
degree of fredom df = 22 -1 df = 21
and α = 0,1 t(c) = - 1,3232
To compute t(s)
t(s) = ( μ - μ₀ ) / s /√n
t(s) = ( 396 - 405 )*√n / 21
t(s) = - 9 *4,69 /21
t(s) = - 2,01
Comparing
t(s) and t(c) - 2,01 and - 1,3232
|t(s)| > |t(c)| then t(s) is in the rejection region we must reject H₀

Find the slope of the line that passes through each pair of points. (-3, 1 )and (-17, 2)
Answers
Answer:
1/-14 or 1 over - 14
Step-by-step explanation:
The equation you need is: y2-y1 over x2-x1
So if you plug it in it becomes 2-1 over -17 -(-3) so 2 - 1 is 1 that's the easy part, 17 - (-3) is the hard part because you can't minus a negative. So it becomes -17+3 which is still -14 because you take the sign of the bigger number. Sorry if it's hard to understand :(

You have to split it up per box. Therefore dividing it will show you how much each box costs.
find the slope please
Answers
The slope of the line is 2.
The slope is going up from left to right, so it'll be positive to start with. From there you have to do rise over run. That is pretty much how many units up and in towards the slope do you have to go until you find 2 points that are in the center of the line. In this case, the rise over run is 2/1 which equals 2.

A doghouse is to be built in the shape of a right trapezoid, as shown below. What is the area of the
doghouse?
Answers
You need to add the top length and the bottom length, and then multiply that answer by the vertical height of the shape.
7 + 10 = 17
17/2 = 8.5
8.5 x 7 = 59.5
You can also double check this by working out the area of the square and then the area of the triangle, and adding them together.
7 x 7 = 49
7 x 3 = 21
21/2 = 10.5
49 + 10.5 = 59.5
